Part of the John Deere Repair Manuals.
This is the factory Diagnosis and Tests manual (TM series) for John Deere 5425, 5525-family and 5625 tractors, covering the 5425, 5625, 5725 plus the HC high-crop and N narrow versions built 2005 to 2008. It is the book dealer techs use to chase problems, not to tear parts down: trouble codes, observable symptoms, and step-by-step tests for the engine, fuel and air, electrical system, the CCU/HCU/PTR/EHC/ICC control units, all three transmissions (Collarshift, SyncShuttle, PowrReverser), drive systems, steering and brakes, hydraulics, and the cab. The Electrical section (pages 511-512) covers wiring schematics for the ignition, charging, control and related circuits. You also get hydraulic schematics, theory of operation for each circuit, and the spec tables to test against, like main relief pressure of 18 995 to 19 685 kPa (2755 to 2855 psi). Service tool and dealer-fabricated tool lists included.
